Who is a card that you weren't expecting much from but dominate with?
Mine would be the Cavan Biggio diamond...bombs galore
jackson rutledge #NASTY
Adley Rutshsbehbsman or however he spells it
42 Niko Goodrum
Prime Garrett Anderson has been an offensive machine
I've used just about every card in the game with a decent sample size in all kinds of spots in the order, but the one player who has never been outdone is Jasson Dominguez. He leads my team in basically every stat (I think Ortiz has him in slugging % by a small margin), both counting and rate and passes the eye test with flying colors. He plays unreal defense and has a cannon of an arm. He was my first superfractor and I don't see him leaving my outfield all year.
I don’t know if you’d consider him a sleeper but Trea Turner live series card is probably my favorite in the game so far.
Xander Boegarts for me.
Only used him in BR so far but I'm going to second the Milestone Biggio card. One of my favorite low BR diamond selections.
Early on - Trea Turner and Jasson Dominguez hit well above their stats imo. I've currently benched Trea for Tatis/Jackie (seriously considering putting him back in for either of them).
